To all tti/1.0m t may concern e-it known that Ylr, WILLIAM S. WESTON, a citizen of the United States' residing in the cit37 ot' lJallas, county ot' Dallas7 and State of Texas9 have invented certain new and useful improvements in f'nticreepers for Railway Rails. of which the following is a full.. clear, andexact description.

My invention relates to improvements on the Vtorm spring clamp anti-creeper set forth in U. S. Letters Patent No. 1,257,566 granted to me Feb. '26. 1918. The objects of my present invention are improvements in certain details of the construction of the device, therein illustrated. described. and elain'led, which do not change the combination and relation of the several parts but which permit of a new and improred method of installation and a more perfect functional operation. The full construction of the anti-Creeper'embodying these improved details, and the method of installation are hereinafter described and clearly illustrated in the accompanying drawings which form a part of these specifications. The novel features are particularly pointedout in the claims. l

ln the drawings Fig. l is a side elevation oi a rail showing the antifcreeper in position against the tie. Fig. 2 .is an elevation as seen trom the lelt of Figjl with ythe tie omitted. Fig. 3 is a plan view ot' Fig. 1. l? ig. transverse to the rail, similar to Fig. 2, with the rail indicated by dotted outline, drawn to .illustrate the manufactured shape and re lation of the parts". lliigs. 5.

The same numerals ot' reference indicate the same parts in the several views.

Described in general terms my anticreeper is a V-forrn spring clamp device. made of resilient material. provided with three seats for bearing against the rail base edges, one seat at or adjacent the root ot the if' and one at or adjacent the free end ot' each arm or member. In the manufactured shape the rail seating'A spare between these three. seats is 4.- is an elevation' less than required by the rail on Serial No. 572,476.

which the device is to be used, and it therefore has to be sprung into position when being installed. The spring reaction estab lishes a friction seats. and because of this friction grip two of the seats on opposite edges of the rail base are established as the fulcrums of a lever grip which becomes effective in fumo` tional opera-tion. vention has to do with improvements inde tails facilitating the installation and provid ing for a more peitectl'anctional operation.

The anti-creeper is made preferably from a round rod ot' spring steel act shape in a forging or bending machine. Referring to Fig. l where it is seen in plan view the V-t'orm has one arm or member,v indieated by dotted outline and marked bj1* the numeral l. extending.transversely beneath the rail and a second member il extending lon-lf gitudinall)Y adjacent the edge ot' one of the rail base flanges. The root ot' the V at 3 andthe adjacent portion'o the longitudinal member is offset upward from the center of the transverse member, as seen in Fig. l, so as to form a shoulder seat a adapted to bear againsty one railbase edge. while the free end of the transverse member is bent upward at 5 to Aform a shoulder Y against the opposite rail base edge. The distance between the seats Lt and 6 is somewhat greater than the width. ot the railbase so that when in operative. position' and bearing against the edges the transverse member will 90 lie at an angle with the rail slightly less than ltldegrees. The free end of the long1- tudmal member 1s inclined downward and Inade with suliieientlength of stock to be bent and formed into' a special shape adapt- 95 ed to several purposes. as will be described, one oliu'hicli' is to provide a third seat T adapted to bear against the same rail base edge as the seat t at the root of the V. In

forming the seat]- the extra length o member 2 is lirst bent into a loop or eye 8 located beneath the rail base flange and adapted to art as the tie abutting portion. The end of the stock is then bent up 'ard past the edge ot' the rail base at T 'l`he extreme end of the portion Tb is curved or hooi-:ed baclmvard on a line which it' produced would extend above the transverse member. The upper portion ot' the loop 8, marked the parts T" and Tb form the three sides ot a Aflange embracing jaw in the bottoni of which grip'on the rail at the three il" As stated my present in @5 worked into en seat (i adapted to bear 95 and over the top at i".

on the drawings. together with is located the seat 7 for bearing against the rail base edge.

Seat 7 is a jaw seat in the sense that the top and bottom portions 7b, and 7C converging into the part 7 form a tight tit at the edge of the rail base and provide against any vertical movement at the seat.` Seats l and 6 are shoulder seats, as in conjunction with Athe transverse member they provide bearings on the bottom and edges only of the .base flanges. With its top portion curved back as described the jaw seat byv its connes tion to the transverse member through the medium of the loop and longitudinal member serves under normal conditions to hold the transverse member up against the base of the rail with the shoulders in operative position. The shoulder seat 6 on the free end of the transverse bar is provided preferably with 'a short nosing'or projection 13 adapted to overhang the edge of the rail base flange. This nosing does not enter into the functional operation and. its sole purpose is to provide against the seat working out of position under abnormal strains.

One ot the prime features of improvement in my present invention will be found in lil the exact construction of the jaw seat as distinguished from the construction illustrated or described in my prioi` patent reterred to. While the jaw is made with a tight .lit right at the edge of the rail base the angle of convergence between the top and bottom parts-7b and 7 is greater than the angle of convergence between the top and bottom surfaces of the b ase flange. By this construction the jaw may have a rocking movement in a rvertical plane transverse to the rail and about a center adjacent the lower filet of the rail base edge. rlhis movement, the range ot which may be seen by comparing the position of the liaw 'in Fig. 2 with the position shown in Fig. 6, is provided or and utilizedsolely as an aid in the installation.

Fig. 4f illustrates the manufactured form to be such that, when the transverse bar with its seats 4 and 6 bearing against opposite base edges is in its operative position, the jaw seat 7 encroaches on the rail space and the top and bottom parts rotated downward. Also the curved end of the .top u part is bent downward Aso that the space between this part and a surface represented by ,the base of the rail resting on the transverse member and in the 'juncture between parts 7a and 7C of the jaw is very much less f than the thickness oli' the rail base llange. This contracte-l shape is necessarily exninded al, installation and its contractile. duality is depended upon to hold the device in operative position.

The installation process in which the jav.' seat is rotated against the resilience ot the `loop 8 and the torsional resilience of the Lenses longitudinal member 2, and thereby sprung outward relative to the transverse member, momentarily expanding the rail seating space beyond that required when finally seated, will now is first placed by. hand with the tree end of the transverse member projecting under the. rail and the aw seat part way on one flange. It is then driven to the position of Fig. T, and that of the dotted outline Fig. 5, by hammer blows applied adjacent the seats 7 and 4 as indicated by the arrows 9 and l() in Fig. 5. In this position because of the contracted-shape as manufactured the hook 5 with seat 6 and nosing 13 will not clear be described. The, device the rail base edge. Hammer blows are next applied to the end of the longitudinal member near its juncture with the loon as indicated b tbe arrow 1G in Figs. G and T. These b ows rock the jaw seat to the position of Fig. 6, contracting the loop 8 more or less at the same time, and carrying the adjacent end of the longitudinal member farther under the edge of the rail base. This-action momentarily rotates the longitudinal member and the transverse member as a whole. about the bearing 4 at the root of the V for a center, from the position shown by dotted outline to the position shown by lull outline in Fig. 5. In this momentary position'the transverse member lies nearer at right angles to the rail so that the 13 will clear the edge. During this last action as the nos ing clears the edge the resilience in the shape brings the transverse member up yagainst the base of the rail, while agfurther partial recovery of its manufactured shape following the last hammer blow brings the device to its installation position as shown 'in` Figs. l, 2,. and 3. f v

It will be obvious that while I preferably use the rocking action of the ljaw seatl sind the compression ot' thedoop conjointly to accomplish the last movement' of the installau t1on just described. yet the compression of the loop alone by the blows at i6 might be. utilized by making the loop larger and more yyielding.

To further aid the installation process passing from the position of Fig. 7 to Fig; (3 and to make the hammer blows applied at 16 more or less cumulative I provide a short bevel lT on the upper end of the hook 5 immediately above the nosing 13. As the blows .are applied at lG this bevel will work up on the lower filet of the rail base edge because of the resilient reaction extending from the rocked jaw through the loop and longitudi nal rnmnbcr to the transverse member.

ln the 'functional operation the movement ot the rail whi h tends to carry the device in the direction indicated by the arrow la, l, is met and held by the tie reacting in the opposite direction on the tie abutting loop as indicated by the arrow l5. This beer Les reacilon, ihrnsl; is lransmlt/ed lo the rail lhrongh the longitudinal member, es indi eaed bythe errow 18, ig. 8, lo the roei; of ille l! e5 3 end einen to he reil through the leverage of ille trensrerse her wila its shoulders el end 6 acting :is fnlcrums. As stated al;v she beginning of these speciiicetions the establishznen'J of the lever grip is contingent on the eslsehlishnien; of a iric lion grip at all 'three seats or hearings on the rail base edges. This friction rrip is a quslity inheren in the device ijssel'. independen oi' 1func-,lional operation and olependenlY upon the contractile quality of the shape. llthe tie reaction were transmitted through ille device in such manner as noi; lo utilize the lever grip the holding' quality would be of small value. That this is so :is disclosed by the fact that ai: the time of installation if the device does not, shui, against the lie, as shown in Fig. 5, il; may he seh up lo the lie by la light top of s hammer et the rooJ ol the if in the direotiono Sche 'arrow 19. ln this aciion no lever grip is developed and only the initial friction has to be overcome.

Referring to Fig. 8 the surfaces of bearings sind (l slightly inclined to the edges olf the rail base, he position of hearing G under the nosing being indicated ley dotted line. This-inclination porinihs the resi por `v:ions ela and il to sink into the rust and scale on, lhe losse edges under the coniracile re fiction at che time of installation.

It may he noted that, While l' prefer to incline `both bearing surfaces l and 6, unsatisfactory operation can he had willi only the surface (l at the free end of the member inclined io the edge or" the standard width of base Wish which it is lo he used. This surface while :made with a smell angle of incline is yet made with the angle large enough to have an incline in the saine direc' tion as illustrated even when the railv in actual use may he found to he rolled lLo a wiillh oi' hase slightly under the standard.
